I have been using Redken products for many years almost exclusively. I will switch in a clarifying shampoo occasionally, but find that the Extreme Shampoo, Conditioner and mask are just right for my hair. I have color-treated hair with about 5-10% gray trying to show it’s dry self when I look in the mirror. Gray hair is sort of wiry and dry, while the majority is thick (lots of dense hair growth) with a lightweight and fine texture. Some shampoos and/or conditioners can weigh my hair down. That is no fun! So I stick with these Redken products and enjoy shiny, healthy and soft hair.
